Application-specific architecture for real-time control of a lime machine

The development of sophisticated real-time control systems requires effective hardware and software systems and design tools. This paper presents the computer-aided design of a microprocessor-based controller for a lime slurry delivery machine. One of the novelties is the originality of control implemented for such types of lime machines. The basic aim in this approach was to ensure high performance, as provided by a special-purpose design, with minimum electronic hardware cost. VHDL models simulations were executed to verify the controller´s design. Validation of the designed system was accomplished through real-time implementation tests. The developed system is aimed to provide direct control of electrical motor and hydraulic pumps that drive the operation of this specific machine. Performance evaluation was carried out in the real machine implementation.
